Root MS345 to H340 - is it possible?

[kasimirpulaski]

Is there any possibility to go back with firmware from version MS345 to H340? I tried to do this with LG Flash Tool 2014, but everytime it ended showing android and LG logos. I need to do this, cause MPCS software has sim-lock, which I can't remove (I'm not from USA and I don't even have an account in MPCS). Sorry for my english btw ;p

You can flash from MS345 to H345 no issue, That's what I did when switching from MPCS to TMo. However, sim-lock will still be there. I had to pay for a third-party unlock to be able to use the phones on T-Mobile since, even though MPCS and Tmo are the same company and on same networks, the phone still recognized that I didn't have a MPCS sim inserted and locked me out.

TL;DR Flashing the phone to a different model/carrier firmware is totally possible but will not get rid of the sim lock
